This is the first actual 2.11 release, (and it's late. The release team apologizes), though garnome and ubuntu breezy (without GTK+ 2.7) have been shipping previous versions. So it's even more important now that people test this as much as possible.

WARNING! WARNING! WARNING!--------------------------

This release is a snapshot of development code. Although it is buildable and usable, it is primarily intended for testing and hacking purposes. GNOME uses odd minor version numbers to indicate development status. Please check the unstable start page for more information:
